10 takes up much more Vroom than is actually needed in the often limited school room,`

An object of my invention-is to provide'a `bench particularly adaptable for the use of manual trai-ning of students 'which is suited for their-needs, strong and 'of a neat compact size Vwith thedesired amount of neces sary space for each student. y l

' AV further object ofmyinventionginorder to conserve room in the school room, istoV 20- provide a double manual training bench conf structed so as to have plenty of room` for a student to work on each side thereof. By thus combining the former benches into a double manual training benchit is possible toconserve a lot of room in the limited space available therefor rin the crowded school room; I so construct my K double manual training bench as to have all the parts necessary for the student within ready reach o each student on each side thereof.' A Y A further object of my-invention is to p rovide a detachable unitary vtool stand normally located in the center of my improved manualtraining bench and readilyreachable v by each student and limited in size to only holding the requisite number yof toolsnecessaryV for manual training4 purposes.

Presentday benches often have many types of protuberances protruding from the upper top surface thereof and a further object of my invention is to `provide,agmanual training. bench to take up a minimumamount of room which may, if desired, have'flat upper surface. Tov this end I'locate suitable vises for eachv student on obliquely opposite ends of each side thereof and I so constructlthe Aupper surface of the movable'portions'of each vise so that it will be substantially level Ywith thebench top in order that-the top of the .benchmay be .available v,to lwork ion sub-V stantially up to the center thereof; I mount 's the unitary work stand heretofore referred to in a longitudinallyv extending central groove in the table. In addition I preferably detachably mount the work standso that it ymay be removed'entirely in case a student de- 'sires to lay a board entirely across the bench.

The unitary work stand is, constructed of such-light materiali and of such a minimum number ofpartsthat it may be removed from this groovebyfasmall child Without diffi- 'Cllllyl'iv i; 2 u W Y I preferably construct the groovewith flat side` edges and the base of the work stand cooperates with'the'flat side edges of substany-65 tially the Widthfof the groove to'retain the tool stand vfbaseyvithin lthe ygroove against transverse displacement. In order to secure thebase ofthe work stand against longitudinal displacementfI pivotally mount arms 570' spaced from Aeach othersubstantially the length of the tool stand base on suitable Jmeans, such as screws located centrally of the central groove, 4,which arms are pivot-able to longitudinal alignment vwithin the groove in .case it may be desired to sweep out' the groove' of shavings andother detritus.

fpAs -stated, I so construct. myimproved i benchtopsurface substantially flat in case it be desired to brace a board end for sawing," planing, or'other purposes.k On the upper surface of the bench, I'provideasuitable brace for this purpose, which in mypreferred embodimentcomprises affT-brace havinga flat V'lf-stem adapted to overlie the bench top sur- `-85 y face for abutftal ofa boardv end thereon and a` T-head of substantial depth preferably countersunk within the upper under surface of said T-stem'adapted'l to "be detachably clamped bythevisejaw surfaces. It isj'thus obvious 90 v.that fthishboard endbrace cooperates with Vv my bench to provide a suitable board end bracetherefor;LV2

YThese and such other objects of my invention as may hereinafter appear will be Vbest 95. understood from a description ofthe. accom-v panyingdrawings, which yillustrate an embodiment thereof. l c y 4In the drawings,.Fig. lis a plan vview of an improved-manualftraining bench constructed 10 50a means to brace a board end thereon.k ,F.or'this feo the brace arms for securingthe detachable tool stand .base against longitudinal movement pivoted tolongitudinal alignment forY cleaning the Vcentral groove thereof.

Fig. 5 is a perspective view of the detachable board end Vbrace I preferably employin' conjunction with' my improved bench.

In the drawings, wherein like characters `of reference indicate like .parts throughout, 10 generally indicates a manual training bench constructed in accordance withthe teachings of my invention.

. As stated, forpurposesof Ysav-ingroom in the toooften crowded school room, I :preferably constructmy improved bench 10..so as Vto accommodate two students,.one on each Vside thereof, although itis apparent that if desired ,the top of the bench lmay .be extended to join a pluralityv of the unit benches shown in'a'row. My improved bench 1() .includes the flat top 12 provided with )the central longi` tudinally extending groove 14 havingthe preferably flat side edges 16. The top 12 of my improved bench is preferablysupported by the legslS suitably Ibraced by the longitudinal braces 20- and transversebraces V27.2.1

g I provide vises 24 foreach student lmounted on obliquely opposite ends 2.6 of each side edge 28 ofthe :top 12 thereof. 'The side edge 28 ofthe top' 12 adjacentthe ends 26 thereof 'forms the stationary vgripping jaw-30 of the vice 24. The vise 24 -is provided with the usual movable'jaw 32 moved as'usual relative to the stationary j aw 3,0 by means of the usual threaded bolt 34 fitted into the usual threaded hole 36 in the stationary jaw'BO and'movable on turning of the usual handle 38. The `1nov. able jaw 32 is so constructed so as to lhave the upper surface thereof substantially level with the top 12 of the 'bench s o when the vise 24 is not in use a board may extend Lflatly Iover the top-thereof.

As stated, as the top surface is normally flat Vit is essential that 'I i providek suitable purpose, I ysupply the board lend T-brace 42 shown in detail in Fig. 5 provided with I vthe flat T-stem 44 Aadapted to overlie the bench top 1.2 Yfor abuttalof aboard endY there- I on and a TV-head 46 of substantial depth A'secured to (preferably by Vcountersinking it therein), the upper under surface ofthe T- stem 44 adapted to be detachably V'cla'. inpedrby the.Y vise jaws. Itis thus obvious that when bench-top'12, that a board end` may be laid {against the flat stern-4 4 toform abracefor side thereof readily available for his use. j my preferred embodiment, I preferably cont-he upper surface of the board. Y

I provide a tool holding stand 50 mounted centrally of the bench top 12 Yhaving a tool supporting' means 52 foreach student on eah n the desired operations such as planing, etc., on

struct the toollholding stand 50 so that it may be readilyremovable and in order that the space on the bench top may be available to approximately the. cente1".thereof, I preferably construct the tool stand 50 with the base-54 adapted to fit within the central longitudinal` groove and having the pref erably flat edges adapted to parallellthe flat edgesV 16 ofthe groove to keep said ybase against transverse movement within the groove.. fThe central support 58 projects up- Vwardly centrally of said 4,base and the Atop 60 mounted centrally on said support 58is provided on each side thereof adjacentthe Asupj port VV58 with thel separate -sets of vertical holes 62 adapted to support tools for each ,student lTon opposite sides thereof,' one setv for .each

student. It is .thus obvious-thatthe uppersur-uface64 of the base `54 as shown in Fig. 3 normally'lies within the ,groover14 below the bench top 20 `so as'ito make the space on leach side Tof thestand 50vavailable entirely up to the centersupport r58 thereof. In addition, 'I

. provide means to-,detachably secure the -tool stand 50 against longitudinal Ymovement within said central groove 14. In myV-preferred embodiment said means comprises the Aarms 7.0 spaced from each Vother'substantially the length of the tool stand base adapted to .abut

Y,when atransverse position the ends 66 of ,the tool stand base 54 'pivota'lly mountedcentrallyof-the groove'14 by means of the screws p 72 andY thus l.pivotable astshown in Fig. .4. into longitudinal alignment with each other within said groove 14, `after removal of sai-d stand 5() from said .groove so that the groove 14 may vbe readily swept clean of shavings or other detritus without 'obstruction from the arms-70. f f -If desired any of the features .explained in detail may be omitted and the tool stand 50 may if rdesired'be detachably or otherwise rsecured, preferably centrally ofthe bench 10 in any suitable manner.

It is understood that my `invention is not limited Lto theV specific embodiment shown and that vvarious deviationsY may be made therefrom without departing from Vand scope ofthe appended claims.
